Definitions

  • Reproducible immobilization is essential to a tighter and more conformed treatment field.
  • a high-energy beam can be repeatably applied to a tumor. This allows for a higher dose of radiation to the gross tumor volume without affecting healthy tissue.
  • Radiolucency is highly desirable and can provide tremendous benefit to a patient.
  • several patient positioning devices contain metallic parts.
  • metallic parts are not desirable, especially if they are in the treatment field.
  • Metallic parts can cause increased elastic and inelastic radiation scattering as well as fluorescence which can expose the patient to unnecessary radiation. While the use of metals can cause unwanted radiation exposure, they can also reduce the desired radiation dose that reaches the target area due to their high radiation absorption compared to polymer and carbon fiber composites used in the present invention.
  • Some positioning devices are constructed of acrylic which provide a lower strength to attenuation ratio than those constructed of carbon fiber composites. In addition, some positioning devices do not cantilever out over a treatment table thereby allowing an unobstructed 360-degree treatment of the head and neck.
  • the only shoulder depression devices currently available include the use of fabric straps. The straps can be imprecisely adjusted to restrict the patient's movement. However, the straps are cumbersome to use, do not sufficiently immobilize the patient and cannot accurately and repeatably position the patient.
  • the present invention overcomes these deficiencies provides a durable patient support device for immobilizing a patient and allows precise, efficient and repeatable adjustability in a light weight carbon fiber composite that is radiolucent.
  • the patient support device of the present invention provides a head, shoulder and torso support and immobilization device that is adaptable to most commercially available treatment tables, is easily adjustable and provides efficient repeatability while allowing 360-degree treatment of the head and neck.
  • the head, shoulder and torso support and immobilization device of the present invention can be constructed entirely of non-metallic components and provides exceptional radiolucency.
  • the present invention provides a patient support device for accurately and repeatably positioning a patient on a treatment table, comprising a base frame adaptable to be secured to a treatment table; at least one adjustable shoulder depression device retentively secured to the base frame; and a headrest frame that is adaptable to receive a head restraint assembly.
  • a preferred embodiment of the present invention optionally provides a torso positioning device for further restricting a patient's movement.
  • Yet another embodiment includes a patient support device further comprising a buttock restraint means.
  • a further embodiment includes a patient support device wherein the headrest frame is a pivotable and angling head immobilization device comprising, a base frame adaptable to be secured to a treatment table; at least one indexing ladder retentively and detachably secured to the base frame; a pivotable headrest frame secured to the base frame that is adapted to receive a head restraint assembly; and a slide locking mechanism with at least one index tab for use with the indexing ladder.
  • the headrest frame is a pivotable and angling head immobilization device comprising, a base frame adaptable to be secured to a treatment table; at least one indexing ladder retentively and detachably secured to the base frame; a pivotable headrest frame secured to the base frame that is adapted to receive a head restraint assembly; and a slide locking mechanism with at least one index tab for use with the indexing ladder.
  • a further embodiment includes a shoulder depression device for use with a patient support device comprising a notched slide arm that can be retentively received by the patient support device.
  • FIGS. 1 and 2 are illustrations of a typical assembly of the present invention.
  • FIG. 3 is an illustration of one aspect of a shoulder depression device of the present invention.
  • FIG. 5 shows a head restraint assembly attached to the base frame.
  • FIG. 1 shows the patient support device of the present invention for use with a patient in the supine position.
  • the patient support device of the present invention consists of a base frame 12 .
  • FIGS. 1 and 2 depict a one-piece construction of the headrest frame 40 connected to the base frame 12 that is adaptable for receiving a head restraint assembly.
  • the present invention also considers a two-part construction with the headrest frame attached to the base frame 12 by various attachment means.
  • the present invention contemplates the integration of an angling head immobilization device to the base frame in order to further manipulate and repeatably position a patient.
  • the head restraint assembly and the angling head immobilization device have been fully disclosed and described in an application Ser. No. 10/287,063, filed on Nov. 4, 2002, as Anholt-4 now issued as U.S. Pat. No. 6,698,045 to Coppens, et al.
  • the present application hereby incorporates that application in its entirety.
  • the present invention also contemplates the inclusion of a support device that prevents the pressure placed on the patient's shoulders from causing the patient to slide inferiorly down the board.
  • a support device that prevents the pressure placed on the patient's shoulders from causing the patient to slide inferiorly down the board.
  • This can be accomplished by the addition of a buttock restraint means 70 .
  • the buttock restraint means can be a simple raised pad attached to the base frame 12 or a more complex shaped or molded design that cradles the buttocks so that inferior movement is restricted.
  • the buttock restraint means can be indexed for accurate and repeatable positioning.
  • FIGS. 1 and 2 show the depression post 14 as a vertical tube positioned at the one end of the shoulder depression device 16 .
  • the present invention contemplates various depression means including a shaped tube, post or bar that curves around a patient's shoulders and can extend to the upper torso. With this alternative embodiment, the patient's upper body movement is further restricted by pressing the shoulders to the surface of the cantilever board and toward the feet.
  • the appropriate depression of the shoulders can be accomplished with various designs including a bear claw shape and other obvious design alternatives.
  • FIG. 3 shows a preferred embodiment of the shoulder depression device 60 which is a bear claw design.
  • the bear claw design includes the notched slide arm 30 with a shoulder post base 50 attached at one end.
  • FIG. 5 shows a head restraint assembly 80 attached to the headrest frame 40 .
  • the head restraint assembly 80 includes an angling head immobilization device with a U-shaped insert 82 and a deformable thermoplastic mask 84 attached to the U-shaped insert.
  • the head restraint assembly is attached to a one piece construction of the base frame 12 and headrest frame 40 .
  • FIG. 6 shows the U-shaped insert 82 attached by retaining clips 72 directly to the headrest frame 40 .
  • the thermoplastic mask 84 is stretched over and immobilizing the patient's head.
  • the patient support device of the present invention 10 can be attached to most standard patient tables or couches by various attachment means.
  • the securing means can be a removable device or it can be integrated into the base frame 12 with appropriately placed holes and pins so that it universally fits most common patient tables.
  • the patient support device of the present invention is adjustable in several ways. First, the device can be adjusted to fit most commercially available treatment tables. This adjustability provides complete flexibility in that the device of the present invention is self-contained and fits most existing procedure tables. There is no need for retrofitting or additional clamping or securing means.
  • the patient support device of the present invention adjusts on two sides and can easily be centered on a procedure table because of its two-way adjustability.
  • All components of the present invention can be non-metallic although some metallic parts can be used if they do not disrupt the performance of the device. Performance of the device is directly influenced by the material used for its construction. Lighter elements are preferred over heavier elements. For example, the lighter elements in composites and polymer materials result in less elastic and inelastic radiation scattering compared to materials containing metals or alloys. In addition, fluorescence is reduced. For example, when a metal atom is impacted by radiation, it absorbs the radiation energy by ejecting an electron from its shell in the atom's electron cloud. When an electron falls back into the shell, radiation is emitted. This effect is known as fluorescence.
  • the individual components can be selected based on the intended use of the device but typically are crafted out of materials that provide exceptional radiolucency, such as carbon composite. This particular feature is especially important if a highly oblique angle must be used for treating the patient where the device could come into the line of the high-energy beam.
  • a radiolucent device allows imaging and treatment of a patient through the patient support device. This increases the treatment flexibility by allowing an accurate attack of the cancer or tumor from all aspects and angles.
  • the present invention can be used in conjunction with most available tables as well as most available accessories that can be used with the patient support device.
  • One such accessory is a readily available deformable low temperature thermoplastic mask.
  • One such product is a specialty mask currently sold by WFR/Aquaplast which can be attached to the present invention.
  • the thermoplastic mesh mask is formed to fit the patient's features and dimensions and is attached to the headrest frame 40 in order to restrict the patient's movement and accurately and repeatably position the patient for treatment.
  • the attachment means can be one or more clips 72 , as shown in FIG. 4 , or any other means recognizable by one skilled in the art.
